Amino acids are essential for protein synthesis and muscle development, so they’re important for athletes and anyone engaged in physical activities. In fact, they’re known as the ‘building blocks’ of protein and are crucial for building or maintaining muscle mass.

There are two types of amino acids: essential and non-essential. Essential amino acids can’t be made in the body, so we need to get them through food or supplements. Our amino acid tablets and capsules are a convenient and reliable way to get your ideal daily dosage.

Supplementing with both essential and non-essential amino acids can enhance performance in sports and activities. Our diverse range of high-quality amino acids includes essential aminos, BCAAs, liquid formulas, complete amino acids, and individual amino acids.

At Holland & Barrett, we are dedicated to supporting your athletic endeavours and overall well-being. Explore our offerings to find the amino acid supplement that best suits your needs and goals.

FAQs

What are amino acids?

Amino acids are organic compounds that serve as the fundamental building blocks of proteins within the human body. They also play a crucial role in various physiological processes Our bodies utilize a total of twenty amino acids to maintain and support health and fitness.

What distinguishes essential and non-essential amino acids?

If you have previously encountered information about amino acids, you may be familiar with the terms essential, non-essential, and conditionally essential amino acids. Essential amino acids, comprising nine in total, are indispensable for our well-being. Since our bodies do not produce these nine amino acids, they must be obtained through dietary sources or supplements. Animal products such as meat, eggs, and cheese are particularly rich sources of these compounds, making amino acid supplementation beneficial for vegans. Non-essential amino acids are naturally present in our bodies, eliminating the need for additional dietary sources.

What are BCAAs?

BCAAs, or branched-chain amino acids, consist of three essential amino acids: valine, leucine, and isoleucine. These amino acids play a critical role in muscle formation, making BCAA supplements a popular choice among bodybuilders and fitness models. Consuming a ready-made BCAA drink or BCAA powder can aid in muscle development and reduce fatigue. The energy boost provided by BCAA supplements can also assist in achieving workout goals.

Should I consider taking lysine?

Lysine is another essential amino acid that is commonly found in our diets. L-lysine serves as a building block for collagen and is believed to enhance athletic performance.
